'- In the accompanying drawings, wherein like characters of referenceindicate similar parts in the various views: Figure l is aA diagrammaticrepresentation of a casting and cutting mechanism embodying the presentimprovements; several of the parts thereof being parts which are nowemployed in the well known monotype casting machine; Fig. 2 is a planview of the cutter mechanism forming the present invention, togetherwith certain parts of a monotype machine which are associated therewith;Fig. 3 is a side elevation of the parts shown in Fig. 2; Fig. 4 ,is adetail plan view of the cuttermechanism, on a larger scale than thepreceding figure; Fig. 5 is a vertical section on the line 5-5 of Fig.l; Fig. 6 is a detail plan view ofthe cutters with the cover platesremoved; Fig. 7 is a detail plan view showing the fixed cutting member'and the guide for the movable cutting member, the latter cutting memberand the cover plates being removed, Fig. 8 is an end view of the movablecutting member; and Fig. 9 is an inverted plan view of the lattermember.

The cutting mechanism herein exemplified includes two relatively movablestrip'cutting and guiding members A and B having channels a and brespectively through which is fed the strip of metal X or other articleto be cut. Preferably, the member A is fixed and the member B mounted toreciprocate across the end of the member A, the member B having aninclined cutting edge b which cooperates with the edge a of the member Ain the severing of the strip X, the operation being substantially ashearing one upon the strip, as will be apparent. The movable member Bis guided in its reciprocations, preferably by strips b2 seated inrecesses b formed in the lower surface of said member, and stops b* areprovided to engage the ends of the member B and limit its movement.

a In practice, the member A is preferably formed of two blocks 10 and 11spaced to provide the channel a and connected with each other by a plate12 mounted upon their upper surfaces, the said blocks having beveledends 10 and 11a arranged to form a gradually-reducing mouth leading tosaid channel.' The member i3 in practice is also preferably formed oftwo blocks 13 and I4 spaced to provide'the channel b, and having a topplate 1'5 suitably secured vto the blocks and connecting them with eachother.

able member B and holds it down in its'.

proper plane of operation.

The cutting mechanism herein exemplified includes, in addition to theparts just described, an appropriate frame by which it is adapted to bemounted upon rods, as e, f,

such, for example, as those which project l from the galley stand E andsupport the galley pan support F of the at present well known monotypecasting machine. When the herein exemplified cutting mechanism is to beapplied to such a machine the galley pan support F is removed from themachine in order to afford room for the cutting mechanism, and after thecutting mechanism has been applied, the galley pan support may bereplaced on the rods e, f in the position shown best in Fig. 2. Theframe comprises side members 20 and 21 connected with each other bycross pieces 22, and is preferably mounted on the rods c, f in a mannerwhich permits the cutting,r and guiding members to be adjustably fixedin position to receive the strip X and sever the same. Such a connectionis preferably effected as follows: The members 2() and 21 are formedwith openings 20@l and 21a which receive the rod e and by which theframe is pivotally mounted on said rod. Said members also hafe openended slots 2Ob and 21b which receive the rod f. Adjacent to theopenings 20a and 21nl are screws 23, 24 which extend upwardly againstthe rod e, and adjacent to the openings 20, 21" are screws 25 and 26which extend downwardly through the members 20 and 21 Vinto engagementwith. the vrod These 'screws coperate with each other, by

their engagement with the rods, to raise or sociated with a monotypecasting machinef and to be operated by certain parts of the latter.Hence I have shown in a conventional 0r diagrammatic way such parts ofthe monotype casting machineA as are, or may be,

utilized without, however, intending there-h by to restrict theinvention to this particular application, thereof. The arts referred toare certain elements' of t e justifyingl mechanism and also the galleystand E and galley pan support F. As is well known to those familiarwith the monotype casting 13o connected witl of agr'm K causes the sameto .movable member B ofthe cutter. ably, the 'end of the arm 31 adjacentto the `end of the cutter member l is bezit downmachine there is.employed in suc-h machine a cross girt, indicated at A(`i`i,ha.ving aperforation g, from which an-air pipe H leeds to a chamber la, in whichis an air 'pin I, the said air pin operating upon a bell crank .l one ofwhose arms is so correlated with a justification wedge lever arm K thatit pushes the said arm .K into operative nrela'- .tion-with a..centering pin leverL which is operated positively by cams M, mounted oncai'n': 'and'iaises the justification Wedge lever arm K when the .latterhas been xi it as described. This raising press the galley triprod Nandthis rod, in vthe mimetype casting macliine,'operates upon a triplever O. The latter in turn shoving the line of type forward; 'I n the-machine referred to there is also a suitable source of supply ofcoiifiprelssedv air, not` shown, which air operates the air pin undercontrol. of. perforations 1n a paper ribbon, or

paper tower, the` ribbon being 'indica ted at P. lVlien the machine'referred to is employed' for operating the cutter mechanism it ispreferred to discoriiiectthe galley trip rod N from the trip lever 0;,this being conveniently aecomplislied merelyY by adjustingtlic set screw0 (See Fig. 2) away from the end of the galley trip rod, vitl beingunderstood that in these machines the .set screw is normallyadjnsted inthe end= offa trip lever so that its end v ivill'e'ontact with the 'triprodaiid'thereby canse the -trip lever to be operated by the trip ,rod.'f v' g In the herein exemplified -fo'rin'of the invention the cutter`mechanism is provided with a lever 2T which Ais fulcrumedat 28.

on the galley-stand E and has one of vits ends provided with a lateralarm 29 which isarranged in the. path of movement of the Ygalley triprofl N. The other end of the le'ver'Q/` is pivotally connected at 3() toan arm 3l vwhich in turn is Connected to the Preferward as shown at 32in Fig. 5. and .is provide-d with a. rearwardly extending bla-de 33having a slot 34 through which projectsV 'a pin 35 rising from the uppervsurface of the member B, the connection bet. \;veen the arm 31 and themember B being. thereby of a lostfmotion nature, it being. noted thatthe downwardly bent portier: 32 is not fastened to the member B. Aietraetile spring 3G is connected'tothe pin135 and to a pin. 3'? on theplatef and effects the forward movement of the member B when the latterhas licenpressed rearwardby its actnaling levers like moyez'vffnt of thesaid levers'lieA ing effected by a. retractile spring 255i whichconnects the endof the arm 3l with one of the (liess members 22 of theframe.

It will non" beA apparent that when the traverse a straight/guidedpathfand the galley trip rod N is operated' it will hy its engagementwith the projection lrom the lever 2,7 press the said lever 'in adirei-.tion which moves the member' B transversely across the endv ofthe member A, the cuttingl edges a and of said members coperating duringsuch movement tocleanlysever from the strip-X a. section thereof of alength appropriete for use as a lead or'iule, the operation of the saidgalley trip rodg': *eing con- '-trolled by perfor-ations iii the'iiibbon P Vv'lieii' the movable member B has been moved to the rear bythe operation of the ari'n 27 it is restored to its former position bythe spring 3G, the said lever '27 beingl ."similarly restored by theSpring 38, ready for another cutting operation.

The extent of the lost inotioninay 150 A beregulated as required to variably determine the length of movements ofthe gate orl blade, by varying the distance between the nuts 0*"` thesaid nuts being adjustable for this purpose.

The front wall of-the mold C is the Section of lead strip previouslycast and to which it is desired to cast another section. In operationmolten lead is squirtcd into the chamber c when the gate or blade c2 isin retracted position and after the metal has been allowed to coolslightly and has become united to the end of the previously castsection, theugate or blade c2 is automatically moved t'orward, forcingthe strip X out from the mold, toward the cutting mechanism, after whichthe gate or blade is again retracted and the chamber is opened to re-`Yceivc another charge ot molten metal, tho

phases ot' movements ot the gate or blade c being properly timed withrelation to the operation of the pump which forces the molten metal intothe chamber c by means which are well known as a part of the lmonotypemachine.

The intervals between thc operations of thc cutting mechanism isdetermined by the distance between the perforations in the ribbon P andin turn control the length of the severed sections which respectivelyconstitute a lead or rule. f

In thc composing machine at present used for producing the perforationsin the ribbon employed tor controlling the operation of the casting andjustifying mechanism of the typeI casting'` machine there is a blankkey, so called. The operation of this key feeds the ribbon but does notperforate the same. In producingthe perforations in the ribbon l forcontrolling the operation of the cutting mechanism, the composer strikesthe blank key the number of llimes which accords with the intervalsdesired between the pertorations and then strikes the justification key,the latter producing the perforation; he then again strikes the blankkey the required number of times, following this with another operationof the justification key, and so on until the required number ofperforations arranged at predetermined intervals have been produced inthe ribbon for the purpose of casting the required number of rules. Forthe purpose of illustration, assuming that leads or rules five incheslong are to be produced and that each operation of the blank keyrepresents a` distance of one-half inch, it will be appar.- ent that,the blank .rey is struck ten times between each striking ofthejustification key.

he casting operations must'be so correlated with. the cutting operationsthat the latter will occur only When'the required len h of lead has beencast into strip form an moreover, must take place during the pauses ofthe step-by-step feeding of the strip by the gate c2. Hence the lengthof reciprocatory movements of the gate is so arranged that each sectioncast will be an even divisor of the length of lead or rule required, itbeing remembered that the length of each section of the strip castaccords with the movement ot' the gate as does the length of eachfeeding movement of the strip: the cutting occurring during thenont'ecding movements of the gate or while the gate is stationary.
